Abstract

The invention discloses a mouse device, comprising a control chip and at least one control component, wherein the control chip comprises a voltage detecting circuit; the voltage detecting circuit is coupled with the control component by at least one multiplexing connection foot; and the voltage detecting circuit is utilized for detecting at least one voltage value on the multiplexing connection foot so as to judge the operating state of the control component.

Description

technical field [0001] The present invention relates to a mouse device, in particular to a mouse device capable of sensing the voltage value of at least one multiplexing pin of a control chip, and judging the operating state of at least one control component accordingly. Background technique [0002] The mouse device usually includes a plurality of control components to meet diversified operation requirements, for example, it may include a plurality of buttons, a mouse wheel, and a light emitting diode corresponding to an operation state. Therefore, the mouse device usually includes a mouse control chip to detect different operating states and control the actions of the coupled electronic device accordingly. [0003] In order to be able to detect different operating states, the control chip of the known mouse device usually includes a plurality of pins to respectively detect the triggering states of different control components. For example figure 1 A conventional mouse co...
